HEADLIGHT.

Application filed September 11, 1923. Serial No. 662,148.

To all 'wiz-om it may concern.

Be it known that I, WILLIAM D. BAKER, a' citizen of the UnitedStates, and a resident of Vernalis, count)l of San Joaquin, lState of California, have invented a new and usefiilHeadlight, of which the following is a specification.

This invention relates to vehicle headlamps and-has for its primary object the provision of a head lamp for projecting a beam of light in a` rearward' direction so as to illuminate the vehicle togive a'visnal outline thereof to pedestrians and ldriversin front, and to this end, the invention is characterized by novel means which will satisfactorily function as aforesaid, and at the same time illuminate the roadway directly in front ofthe vehicle and to Athe respective sides thereof.

A still further object of the' invention is to provide a novel form of head lamp of this character which, aside from functioning as previously stated. herein, will eliminatethe objectionable glare ot the light ra Vwhich is so freilently thelcause of acci ents upon public ighways by the drivers of automobiles and pedestrians being temporarily'blinded by the glare of light.

Heretofore head lamps have generally consisted of a clear glass lens behind which is placedl a light source and reflector, the parts functioning to project a very brilliant ight in a forward direction or a beam of light almost on a horizontal plano to the roadway and for n considcrable distance inl advance of the vehicle on which the lamp is mounted. In carrying my invention into practical provide means which, in effect,

entirelyl conceals the light source to the eye of the lobserver in front of the vehicle, or to at the same time clearly illuminates the vehicle 'with which my improved lamp yis equipped so that the vehicle is clearly discermble for a considerable distance in advance thereof, and 1n fact such distance as' is found necessary for the gauging of traff fic conditions upon a highway without invitin collision of vehicles travelling respectlvely in opposite directions.

A, still further object 'of the invention is to provide a vehicle head lamp which will eliminate the objectionable forward glare of light in thee es ofthe driver of an ap- Vroa'ching vehic eand intheeyes of peestrians crossing the highway and at the jecting top wall (19).

same time cause such distribution of light upon the highway as to enable the driver 0 the vehicle to properly visualize road conditions to the front and at either side Without fear of accident. l

My invention, therefore, comprises certain new features of constructionv andarrangement and combinati-on of elements hereinafter set forth and pointed out in the claims annexed hereto.

indicates the forward portion of an automobile orf similar vehicle. My improved head' lamp is indicated at (11) and is preferably mounted on a line approximately with the top of the-radiator, and/ slightly above same and as illustrated is disposed on a vertical line in front of the radiator. The purpose of this arrangement will appear as the nature of the invention is better understood. The head lamp principally consists of two, coacting sections (12) and (13),'the latter being somewhat in the nature of a shutter or anti-glare plate of opaque or non-transparent material and same is hinged along its upper edge at (14) to the forward part (15) ot the section (12). The said forward part (15) is hinged at (16) .to the companion part (17) 'of said section (12).

The section (12) is somewhat in the form of a housing and the part (17) thereof is formed with a relatively short bottom wall v(18) and a slightly1 The part 15) comprises a top wall (20) and substantiallv parallel side walls 21-21). It will thus be observed that the said part (15) is open along its entire bottom and that the forward portion of said art (15) is, in eiiect, closed by the aforesaid shutter or anti-glare'section includes a series of equi-distantly spaced lamps (23), or this source may consist of section through longer forwardly prosimply one or any vsuitable number of lamps et i ment is also such that in addition to t is as may be decided. to be most eiective and appropriate when used in connection with the component instrumentalities 'of my invention, and as may he determined tvo give rise to the creat-ion. of the requisite amount of light to snit the requirements or taste oi a particular user. l

It will be observed upon reference to Fig- Y ure 2 that the shutter or' anti-glare section (13) is approximately on a lmrizorga-l line drawn Athrough the longitudinal axe of the lamps (23). It will also he 'oliiserred that said section v(13) is provided iny suitable spaeedrelation to its inner surflce with a' mirror or suitable form of reflector (Q4) and that coacting therewith at the` ends thereof are tilting or angular-ly, adjustable reflectors (Q5-25) as shown clearl/j.' in Figure 3 of the drz'lw'higs.` The mirror (24) is fixed .with Arespect, to the reacting side mirrors (25) and extends across the path of lightA projection of a plurality' of the lamps (23). The side reflectors 25) are preferably disposed in line with the respective end lamps (23). As previously stated 4the part 15 of the section 12 of the head lamp is formed' with an open bottoni permitting theA respective l'mirrors 524 and 25 to reflect certa`n lie-ams of light rearwardly and lto one side of' the vehiclelt), other beamsl of light tothe other side of the vehicle and the bulk of the beams rearwardly onto vthe roadway'in ac cordance with .the angularity of the shutter or anti-glare section 13. At'lthis point it shall be observed that each 'of the lamps is rovided with a suit-able Well'known form o reliector (Q6) which functions ,inV 'view of the open bottom formation 0i the part (15) tofcause a beam oli/ght E to he projected ,forwardly and dtyvt'nwardly onto the roadway. from beneath the 'lower edge of the said"shuttelI or anti zelare section ('13). It isV now understood that due to the f respective angularities of the mirrors (.24)

y and (V25-25)?/their relation tothe lampsl (23) and the `function of the reflectors (26)q light-will be projected so as to illuminate l `the vehicle. (l0) and permit the outl'ne of i.

same "to heclearly'visualized for a great distance*` 1n fronto the vehicle. The arranve f functioning of` the com onent parte of my invention the beam of ight E is projected j vdownward at anangle below the-horizontal Y plane ef the-lamp so as to prevent this beam' r fromheng projected into theeyes of an advancing driver 'or `highway andy it so il uminates the highway v as to rmake the conditions thereof elearlydiscernible 1am t estrians crossingV a to 'the eye of' the driver behind, the

A

In `the modified form of my invention shown in Figure 4, l pro 'ide a substantially closure lile structure (3Q) adapted t'o he secured much in the fashion of a 'visor to the -Airont. of an'ordinary head lamp (33). The

essential features of novelty of this form of.

my invention are in agreement with correspending features of the first said termv` but for the purpose of simplicity the device may be formed from a single strip of' sheet material and same is provided with an open bottom (34) and an .angularly disposed section (352 the latter corresponding wfth `the section '12) inthe iirst embodiment ot'lmy invention. and the inner surface thereof may v he painted White or it can becoated with n any suitable paint orV substance that would enable it to serve as a reflector o light. if

lilo

desired llass may he used as employed in the firstaem odiment. In this form the device may be detaehably secured to the head lamp (33) by means of suitable astenings (36).

While l have shown certain embodiments of my invention, I Wish to have` it undet'-,

stood that various changes or modifications ma `be made within the scope of the claims hereto attached without departing` from the 's rt i i the invention. I lil' im A: j. j 1.
